“We urge you not to pardon Edward Snowden, who perpetrated the largest and most damaging public disclosure of classified information in our nation’s history,” the letter states. “If Mr. Snowden returns from Russia, where he fled in 2013, the U.S. government must hold him accountable for his actions.”

The letter continues, referring to Snowden not a whistleblower, rather a “criminal” who “stole 1.5 million classified documents from National Security Agency networks.”

In conclusion, the lawmakers wrote:

“America’s intelligence professionals take Mr. Snowden’s disclosures personally. We share their view that a pardon would severely undermine America’s intelligence institutions and core principles, and would subvert the range of procedures in place to protect whistleblowers.”

In addition to the letter, the House committee also announced that it had unanimously voted to adopt the findings of its two-year investigative report on Snowden’s actions. The majority of the report is classified, but an unclassified summary report was also released today.

“Contrary to Snowden’s self-portrayal as a principled whistleblower, the report reveals that he was a disgruntled employee who had frequent conflicts with his managers and was reprimanded just two weeks before he began illegally downloading classified documents,” the committee said in a press release accompanying summary report.

The committee says its report also found that a great majority of the documents stolen by Snowden had no connection to privacy or civil liberties.
